'Application filed A."May `28,

The present inventiony relates to vehicles, and more particularly Yto an improvedcarrier'or support or-use'asan`- auxiliary can rier-fortheyehic'le. i

An object of the present invention is to provide la vehicle frame or body with a pluralityV of supporting members which may be vexteii'ded or collapsed, so that they may bequiclly land easily brought into-position forcarrying additional load and whichmay ybe quickly moved` out of the waywhen not iii-use, and so asto lie withinthe normal dimensions of the wagon or truck.

v Another object ottheinvention-is to proyidevra :wagon box or body with 'extensible supports,"wh`ich may be drawn out from the sides of the body to carry'lumber, pipe, structural iron beams7 or lthe like `which can not be conveniently carried in the body, and means for releasablyho'lding the'supports in extended'and contracted or folded -po`sition.

Another object of the invention; is to provide auxiliary foldable 'supports oi' this character, which may be builtinto the vbody holsters orinto the ramefstructureof the wagon or truck, so that thebolsteror-rame structure may befutilize'din partffor holdmitof its free adjustment. n s. A Y'further object ot the inyentioni's to arovide 'an lextensible"support for wagon bodies' which may be construotedforapplioationto trucks and wagons already in use,

ing the support in proper positionan-d'ad-vr and vwithout material modification Yof the same, the inventionl an attachment. y, p

With the foregoingand otheij `bjeots in Vview, theinve'ntion A'will befmore ullyjd'escribed 'hereinaftenend "will be more particularly pointedA out in the claims' appended hereto. 1 Y

s Referringto the' drawings, l10 designatesa wagon frame shown in thepresentinstanoe as comprising a pair of longitudinal sills or beams and across the upper edges ofV which are'mounte'd spaced apart "transversely disposed bolsters 11 upon which the wagonbox 12 isdire'ctly mounted. The `holsters 11, in the usual manner, extend'slifghtly beyond theoppositesides of the wagon box 12am?.

cariyvbiaces -13 which extend upwardly and` inwardly to the 'sides of the k'wagonfbox 12 for securing thekv latter upon the holsters 11." Any numbero these braces' 1? 'may be' used the f saine being shown in the- `presenty instance as -fdisposed jonlyfat the" opposite corners of the wagon bddy.

' Vhila*theintention' is 'iapplilfable to tarilons types of wagons,fthepresent illustration Shows one" type l and wherein the auxiliary supports have la fra-nie structure whiohl'eornprises certainof thebolsters. lTheseholst-ers may be' mounted upon the frame 10 beneath the wagon box as supplementaltothe usliali holsters 1l, or, `vwherrbuilt' originally int-o thewagon structure,-1nayfoomprise Cer-v tain ""o'fft'he fusual Ibolstens employed. In either case; the invention comprises a frame madefupoif Aapairl of holsters 14 closely spaced apart by `straps-or endplates 15 'se-y cured by boltslG--a'cross the opposit'eends of edges ofjsaid ends, so that the space between thebolsters 14 is free and uninterrupted at the trame and in which are mounted a pair of eXtensible supports 17 slidable through the j opposite ends ot' the frame and which are cutaway or recessed as at 18 at their inner ends and in their opposite faces to provide tongues 19 adapted to overlap when the supports 17 are slid inwardly toward each other into the trame.

The holsters 14 which comprise the support framev have longitudinal slots 2O which are disposed intermediate the ends ot the bolts and through which project stop bolts 21 carried upon ther inner ends of the tongues and projecting `outwardly through the slots 20, sleeves or rollers 22 being mounted upon the shanks ot the hoits 21 where they pass through the slots 20 to reduf'e frictional contact between the bolts and the holsters 14.

llVashers 23 are mounted on the outer Aends of the bolts 21 and are held against the outer sides of the'bolsters 14 by nuts 24. yThe heads of the bolts 21 are relatively ilat so that the boltsk may pass each other during the collapsing of the supports 17.

Each bolster 14 is provided near one end With the locking bolt 25 and which carries a spring 26 seated in'a socket 27 formed in the inner side of the bolster 14- and which engages a flange 28 near the inner end of the bolt 25 for normally urging the latter inwardly into engagement with the adjacent support 17. The support 17 is provided with y notches 29 adapted to register with the inner end of the bolt 25 into various positions of adjustment of the support 17, so as to hold it tirmlyV in adjusted position. The bolt 25 `extends outwardly from its holster 14 a distance suiiicient to permit-ot the grasping of the bolt to withdraw it from the socket 29 when it is desired to slide the support 17 into extended or contracted position.

Each support 17 maybe providedY with spaced sockets 30 in its upper tace adapted to receive the lower ends of stakes 31 adapted to be positioned in the support 17 and which are used in pairs with a chain 32 connecting the upper ends ot the stakes to hold theV latter from spreading under pressure of a load which is placed between the stakes. j `The auxiliary carrier is adapted to be placed beneath the wagon box 12 with a car-Y rier frame beneath each end portion of the .wagon box, although any number of thev devices may be used according to they length of the wagon box or body and according to th nature of the material to be carried.

In the present instance a carrier trame is mounted beneath each end of the wagon boX as shown in Figures 1, 2 and 4. Normally the supports 17 are contracted or col` lapsed into the carrier trames and with the tongues 19 in overlapping position, as shown in Figure'2. The supports 17 are of such length that when collapsed they do not eX- tend beyond the ends of the holsters or carrier frame, and consequently do not increase the width of the wagon or truck structure. The supports 17 may, of course, he ot any suitable length and preferably dependent upon the widthoi1 the wagon or truck, so as to comply with any traffic requirements as to lateral load extension or with other limitations relative to the character of the work and the structure of the vehicle.

it is obvious that various changes and modiiications may be made in the details ot construction and design of the vabove specificallydescribed embodiment oit this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed iszj 1. An auxiliary carrier for wagon Vboxes comprising spaced holsters arranged in pairs beneath the oppositev ends ot the wagon box, supports slidahly mounted between each pair oi holsters and slidahle lengthwise thereof into position to project beyond the ends ot the holsters and the sides of the wagon box for receiving a load and adapted to be slid inwardly between the holsters out of the way when not in use, means for guiding the supports in slidingmovement, and means for releasably holding the supports in extended and contracted positions.

2. A holster comprising separated fixed slotted members, supports slidable between and beyond said fixed-members, and. guide means onV the supports projecting into and guided by the slotted portions oi the fixed members.

3. A holster comprising separated fixed members, supports slidable between and beyond said xed members, and Vguide means for the supports.

gli. A bolster comprising separated iixed members, supports slidabie between and lbeyond said fixed members, and guide Ameans on the supports moving in the members and acting to restrict the outward movement of the members. Y

5. A bolster comprising a hollow openended bolster body, supports slidable in and beyond the body and having offsetoverlapping parts and means to restrict the movement of the supports.
